Description | ||||||
We carried out the E373 experiment at KEK and detected seven double-hypernuclear events. Only the NAGARA event was uniquely identified as a He hypernucleus among them. For some events among the other six events, unique interpretation of the nuclide would be possible if one of daughter particles from production or decay vertex was identified uniquely. In order to obtain more information about the -interactionwe planned to detect about one hundred double-hypernuclei in the J-PARC E07 experiment, and obtain new knowledge for the -interaction, which is independent of the information obtained from the NAGARA event. To study the -interaction with more nuclei which are uniquely assigned, we are developing a particle identification (PID) method which identified daughter isotopes by the measurement of energy losses in the emulsion. Track width which reflects energy-losses will be measured from stopping point up to ~100m with an image processing method. Under the assumption of tracks to be made of many cylinders with length of 1 μm, track volume values given by the width are summed up and expected to distinguish light nuclear species such as H, He, Li, Be or B. | ||||||
